Dealing with Data Basic Steps to Using the TI-83 Graphing Calculator

What we are going to cover Graphing functions Data Lists Graphing Lists Regression Analysis Programs

Guess What? Everything you will see today you could do with a spreadsheet or graphing program

1. Lists 6 columns that hold data Data can be manually entered Hit STAT then Edit (choice 1) Use the arrow keys to navigate between lists To clear a list: –Highlight the list name –Hit clear then enter

Some List Data From Me 2 You L1L2L3L

2. Graphing Lists  Hit 2 nd then STAT PLOT  Turn on plot (others off)  Graph type  Data locations  Mark type

3. Setting the window  Manually enter values  Automatically by using a ZOOM feature, such as Zoom, then 9

4. Graph the data  Press Graph (for manually set windows)  or Zoom, then 9 (for automatically set windows)

5. Determine line-of-best-fit (regression analysis): Choose STAT Use the arrow key to navigate to CALC Select the type of statistical operation you wish to perform The operation will be performed on the active plots.

Graphing Functions You can specify an equation to graph Y = button Enter the right side of the equation Use the X,T,θ,n, button to insert a variable Hit GRAPH to see the plot

Programs With programs on the TI-83 –You can automate processes –Share them from calculator to calculator –Connect to and use external devices such as sensors

Transferring Programs Connect two calculators using the link cable Hit 2 nd then LINK Use the left and right arrow keys to choose between send or receive.

Running Programs Hit PRGM Select the program you want to run and hit enter.
